  • Family: Cotingidae
  • Monotypic

Distinguishing Characteristics

Lipaugus pihas are large, dull colored passerines. Screaming Piha is a typical member of the genus; it is visually unobtrusive, but its piercing, distinctive call sets it apart. Both sexes are thrush like in appearance, but with a longer tail, shorter tarsi, and a broader bill than a thrush. Screaming Pihas are uniformly gray, although they are slightly paler on the belly and duskier on the tail.

Similar Species

Screaming Piha is broadly sympatric with Grayish Mourner (Rhytipterna simplex), and these two species frequently are syntopic. Both are gray, long tailed birds and so superficially are very similar. They are best distinguised by voice. The mourner also is significantly smaller than the piha, has a smaller, thinner bill, is more uniformly gray, and has reddish brown (not gray or gray brown) irides. The mourner also frequently associates with mixed species flocks, whereas the piha rarely if ever joins flocks.

Dusky Piha (Lipaugus fuscocinereus) also resembles Screaming Piha, but is much larger and is restricted to montane forests of the Andes; Dusky and Screaming pihas rarely if ever overlap geographically.

Detailed Description

Adult: Sexes similar. The following description is based on Kirwan and Green (2011): Generally gray; remiges, greater wing coverts, and rectrices browner or duskier. Underparts are paler than the upperparts, and are palest on the throat.

Juvenile: Similar to the adult, but has cinnamon rufous wing coverts and tips to rectrices (Schulenberg et al. 2010).


Little information. Molt is seasonal in northern South America (Venezuela, Suriname, and Guyana; males initiate molt from February-May), and in eastern Brazil (where males initiate molt September-December), but there is little seasonality in the center of the range of the species (Snow 1982).
